We'll be looking at the 3 types of stream crossings: at grade (fords), culverts, and bridges. Each type has trade-offs in price, design complexity, pollution prevention, wildlife impact, and stream morphology impact. We'll cover the pros and cons you should consider during the design process so you can make good decisions when crossing streams on your farm projects.
